ENVELOP.

Specification of Letters Patent.

Patented Sept. 12, 1916.

Application filed March 25, 1916. Serial No. 86,726.

To all whom it may concern.'

Be it known that I, CHARLES F. Tarpon, Jr., a citizen of the United States, residing at Bowling Green, in the county of Warren and State of Kentucky, have invented new and useful Improvements in Envelops, of which the following is a specification.

The invention relates to an envelop, and more particularly to the class of safety envelops, packages or the like.

rIhe primary object of the invention is the provision of an envelop of this character wherein the construction thereof permits the sealing' of the same so that detection may be had in event that the envelop be tampered with in an attempt to open the same after the initial sealing of said envelop.

Another object of the invention is the provision of an envelop of this character wherein the construction thereof permits the convenient sealing thereof with despatch and should the Hap be unsealed by surrep` titious opening thereof the said envelop will indicate and enable detection of this fact.

A further object of the invention is the provision of an envelop of this character which is simple in construction, thoroughly reliable and eflicient in its use, strong, durable and inexpensive in manufacture.

Other objects will be in part obvious and in part hereinafter described.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the appended claims.

In the accompanying' drawings: Figure 1 is a plan view looking toward the rear side of the envelop showing the sealing flap open; Fig. 2 is a similar view with the sealing flap closed; Fig. 3 is a sectional view on the line 3 3 of Fig. 2.

Similar reference characters indicate corresponding' parts throughout the several views of the drawing.

Referring to the drawing in detail, the envelop comprises the customary rectangular body 5 forming the front of the same, end flaps 6, bottom flaps 7 and a top or sealing flap 8, the bottom flap being sealed to the end flaps in the usual well known manner. The end flaps 6 are no different from those employed in ordinary envelope, with the exception that the same are provided with convergent lines of perfor-ations 9 which form the separable tabs 10 at the free corners of the said end flaps, while the bottom flap 7 is formed with a separable tab 11 which is detachable therefrom along the line of perfor-ations 12, in a manner and for a purpose presently described.

rThe sealing flap 8 is provided on the inner' face thereof along its marginal edge with adhesive 13, as usual, for the sealing of the said flap to the bottom and end flaps in the ordinary well known manner. On the inner face of the sealing flap 8 medailly thereof is adhesive 14 which, when moistened, will cause the sticking of the tab 11 thereto when the said sealing flap has been closed and l sealed.

The tabs 10 carry adhesive 15 the area of which is slightly removed from the lines of perforations 9, and when this adhesive is moistened will cause the sticking of the tabs 10 to the sealing flap 8 when sealed. In event that any attempt is made to open the sealing flap after the closing and sealing thereof the tabs 10 and 11 will be separated from the respective end flaps and bottom flap at the lines of perforations 9 and 12 so that on the resealing of the sealing flap S, when the envelop is opened by the rightful receiver, the fact will be disclosed that it has been previously sui-reptitiously'- opened by reason of the separation of the tabs. It will be noted that the tab became united with the sealing flap when the same is closed and sealed so that when a knife, pencil or other instrument is inserted under the sealing flap and the latter is broken loose, the tabs will become separated on the lines of perforations 9 and 12 on the opening of the said sealing flap so that when the sealing flap is again sealed the said tabs will remain separated from the ends and bottom flaps, thereby enabling detection that the envelop has been previously opened when the said envelop is opened in the ordinary well known manner.

From the foregoing description, taken in connection with the accompanying drawing, the construction and manner of use of my envelop will be readily apparent and, therefore, a more extended explanation has been omitted.

Having thus described my invention, I claim:

1. In a receptacle, a body having a sealing flap, tabs on the said body and having lines of perfoi'ations foi` the separation thereof from the body, and adhesive substance for fastening the tabs to the sealing flap when closed, said sealing Hap being,` of a, size to extend over the peiforations for coneenling the same and said tabs when the sealing flap is fastened to the body.

2. An envelop comprising a. body having a front, end flaps, bottom flap and sealing Hap, the bottom Hap being` fastened to the end fiaps, tabs formed on the ends and bottom aps, Said ends and bottom flaps being formed With perforations for the separation of the tabs therefrom, and adhesive substance foi' fastening the tabs to the sealing flap when closed, said sealing flap being of a size to extend over the perfoi'utions for concealing the same and seid tabs, Suid peifoiations in the side flaps being disposed in lines diverging and extending from the bottom flap to the free edges of the side flaps.

In testimony whereof I uiiix my signatuie in presence of two witnesses.
